Provide a tailored user interface for Scientific Visualization using ParaViewWeb as backend.


$ npm install -g light-viz

After installing the package you will get one executable LightViz with the following set of options.

$ LightViz 

  Usage: LightViz [options]

To start developing light-viz, first clone the repository:

$ git clone

To set up the dependencies for light-viz run the following. Note that this must be re-run every time the dependencies for light-viz are modified.

$ npm install

When first setting up light-viz for development, it may be helpful to have npm install a symlink to the latest version that can be executed from the command line in the folder (presumably in the path) where npm is located. To do this run:

$ npm link

Now make changes and see what happens. If you have changed the python code that runs on the paraview server side, you will have to re-run the LightViz executable that is generated by npm link. If you have changed the JavaScript code, running the following command and refreshing the page should be sufficient.

$ npm run build

Before you commit, please run:

$ npm run build:release

This creates a minified version of the light-viz JavaScript code in dist/LightViz.js which should be added to your commit.
